Devices of the class referred to are power driven, and are especiallyadapted for use beauty p rlors,barber shops andlikeplaces; andamongthemore important objects of the invention are to provide a device ofthis class that iscompact, and isneat and attractive of appearance; thatis very con"- venient of use, and: is easy of control; that 5 enableshigh quality work'to be speedily performed; that offers no appreciableresistance to the natural movements and different positions of theoperators hands while performing the manicurin'g operations thereby tocon- .za serve the operators strength and v prevent strain and fatigue;and to provide a power I operated manicuring device in which the fileand buffer are reciprocated in much the same way as the correspondingmanual instruments are manipulated.

The foregoing objects, with others herein- 7 after appearing, areattained in the embodiment of the invention illustrated in theaccompanying drawings wherein similar referdesignate corresponding partsthroughout the several views.

elevation, respectively, of a file for use with the instrument, saidviews being on a scale somewhat reduced with respect to that of Figs. 5to 8; and Figs.'-11 and 12 aresimilar views, on the samescale as'Figs.-9and 10, of a b'ufi'erfor use with theinstrument.

The supporting 'structureor, frame of the machine is designatedgenerally by the reference numeral 1 and is in the nature of a hollowcasting whose lower end is enlarged'to provide a housing 2 for anelectric motor 3 shown as supported, with its upper end within anapertureof a web 4 of the housing, by screws that pass through and aresustained by the top wall of said housing. 3 Supported a suitabledistance above the housing 2 by a bracket '8 is a gear case 9 that iscircular in plan and is threaded at its upper end for the application ofa cover 10. The housing 2, bracket 8 and gear case 9 are preferablyintegral parts of the casting that con stitutes the supporting structureor frame 1. Connected, as by a couplingll, to the shaft 12 of theelectric motor 3 is a shaft 13, and the upper end of this shaft hassecured to it, through a coupling 14:, the loweriend of a spindle 15that carries a pinion 16 at its upper end; The spindle 15'is journaledwithin a bushing. 17 that is fitted withina bore in the 9 and which boreis is in alignment With the boss 19 that rises from the top wall of thehousing 2. Supported by and between the bosses 18 and 19 is a sleeve 20that encases the shaft 13. Within a second bore that is formed in thebottom wall of the gear case 9and parallels the previously mentionedbore is a bushing 21 within which one terminal, designated 22, of aflexible shaft 23 is journaled, the body portion 5 p of said shaft beingencased by a sheath 24. A gear25 is fastened to the terminal 22 and Itwill be seen from the description thus .farthat when the motor 3 isenergized itwill 9o drive, through the shaft 13, spindle 15, pinion 16and gear 25, the flexible shaft 23. A

tains a mass or body 36 of suitable absorbent material adapted to besaturated with oil, and from which the oil is conducted by awick 37.through a transverse bore. that is aligned ports in the bushings 17 and;21to the spindle 15 and terminal 22 of the flexible shaft. -Anoilholethrough which the lubricant is adapted to be supplied to the well isshown at 38 inFig. l.

a To the freeendof the sheath 24 isconnlected the stock or handle 40 ofamanicuring instrument designated generallyby the reference numeral41;and the corresponding end of the flexible shaft 23; that is encasedin said sheath is'suitably coupled to amendrel 42 that is journaled in alongitudinal bore of'the stock or handle-40 and carries at its forwardend a crank disk 43, The forward end of the stock or handle 40terminates in a generally rectangular head 14k the top of whichis formedby a removable cover plate 45 that is held in place by screws 46, andextending transversely through the head at is a T-slot within which isguided a slide 4-7 having a forwardly extended neck 48." The neck 48 isprovided with-a bore 49, and is split so that said bore maybe contractedwhen the opposed sides ofthe neck 48 are drawn toward each other bymeans of clamp 50,-saiid clamp involving a thumb screw 51. Theirear faceof: the slidet? has a transverse groove 52 within which a'block 53operates that is carried by a crank pin 54 that eX- tends forwardly fromthe previously mentioned disk 43, said disk being accommodated by anappropriately-shaped recess that'is formed in the rear wall of theT-slot wherein the slide d'foperates,

55.'(Figs. 1, 9and'10) is a'file,havinga shank 56 that is adapted tobeinserted with- .in the bore 49'of-the slide 47 and secured thereinwhen the neck of said slide is contracted by means of the clamp 1 s Abuffer 57 (Figs. 11 and 12) is adapted I to be similarly connectedthrough its shank 58 with the slide l7.-

In the use of the-device, the file is firs attached to the instrument4-1 and the operator then sets the machine in operation by depressingthe'appropriate button 33 of the switch-311:0 close the circuit to themotor 3.

through the connections above described, the mandrel 42 to rotatethe-crank disk 53. said disk rotates t imparts a circular motion to thecrank pin 5 l,and this circular motion of the crank'pin is convertedinto a reciprocatory motion in the slide 41 by reason of the drivingconnection between the V crank pin and slide effected through the block53, that is jcurnaled on the crank pin, and the groove 52 in the rearface of the slide, said block moving back and forthwithin andlongitudinally ofsaid groove inresponse to crank pinin a directionthenailto' beoperated upon. To perform the p-cl shing operation,thebuffer 57 is substitut ed for the file55 and the instrument is 2% issuspended from thegear case 9, and is therefore capable of swinging to,fro [and about with free universal movement, that no appreciableresistance is offered to the movements of the instrument 41 duringthemanicuring operations.
